Technical Field
[0001] This utility model belongs to the field of trash can technology, and in particular relates to a trash can. Background Technology
[0002] Existing trash cans are usually used with trash bags. After the trash can is full, the trash bag is removed manually and a new trash bag is placed in. However, during use, the trash bag forms a relatively closed space with the inner wall of the trash can. When putting the trash bag in, the gas in the closed space is difficult to escape, causing the gas to block the trash bag from the inner wall of the trash can, making it difficult for the trash bag to fit properly against the inner wall of the trash can. Summary of the Invention
[0003] To address the shortcomings of existing technologies, a trash can is provided.
[0004] This utility model is achieved using the following technical solution:
[0005] A trash can includes a base for holding a trash bag and an outer shell fitted on the outside of the base. The base includes a chassis that is detachably connected to each other and a baffle structure disposed on the chassis. Through holes are arranged in an array on the circumferential sidewall of the baffle structure. The through holes are arranged sequentially from top to bottom along the height direction of the baffle structure. The baffle structure has a tapered shape that is wider at the bottom and narrower at the top.
[0006] When a garbage bag needs to be placed inside, the user opens the garbage bag and places it inside the enclosure structure. The user then smooths the inner surface of the garbage bag from top to bottom, so that the outer surface of the garbage bag fits snugly against the inner surface of the enclosure structure. During this process, the smoothing action allows air between the outer surface of the garbage bag and the inner surface of the enclosure structure to be expelled through the holes, and the excess part of the garbage bag is folded outwards to fit over the outer surface of the enclosure structure, thus ensuring that the garbage bag fits completely inside the garbage can.
[0007] This invention utilizes a top-to-bottom arrangement of through-holes in the enclosure structure to create a three-dimensional ventilation network. Combined with the overall tapered shape of the enclosure structure, this forms a top-to-bottom air pressure gradient. With the user's smoothing action, this forces the air between the outer surface of the garbage bag and the inner surface of the enclosure structure to be expelled from the bag-wall space. This transforms the obstructive adhesion action of the sealed air cavity into an active adsorption action between the garbage bag and the enclosure structure, facilitating the full expansion of the garbage bag's internal space for garbage collection.
[0008] Preferably, the fence structure has slots on its opposite side walls, which facilitates the user to apply force to the fence structure, thereby facilitating the user to assemble and disassemble the fence structure and the chassis.
[0009] Preferably, the groove is provided with an annular fastener, which can be embedded in the groove.
[0010] The ring-shaped fastener allows it to be used with the slot. When the excess part of the garbage bag is folded outward and placed on the outer surface of the base, the ring-shaped fastener is inserted into the slot to fix the garbage bag in place. This prevents the excess part of the garbage bag from moving downward due to static electricity or friction during the process of the outer shell being placed on the outside of the base, which would cause the garbage bag to slide out of the enclosure structure.
[0011] Preferably, the inner ring surface of the annular fastener is a staggered surface.
[0012] By setting the inner ring surface of the annular fastener to a quincunx pattern, it can be used with existing drawstring garbage bags. When the user puts the garbage bag in and does not want to add a shell, the drawstring of the drawstring garbage bag can be pulled out and inserted between the outer surface of the garbage bag and the inner surface of the enclosure structure through the inner ring surface. The inner ring surface of the annular fastener prevents the drawstring from slipping out through its own structure, thereby fixing the opening of the drawstring garbage bag and preventing the drawstring from being contaminated.
[0013] Preferably, the upper end of the outer shell is also provided with a skirt structure extending towards the center line. The skirt structure is used to fit against the upper surface of the enclosure structure. The inner side of the skirt structure is also provided with a top cover, so that after the outer shell is fitted onto the outside of the base, the garbage bag can be pressed tightly by the skirt structure, thereby preventing the garbage bag from sliding.
[0014] Preferably, one side edge of the top cover is hinged to the skirt structure, and a fastener is provided between the top cover and the skirt structure at a position symmetrical to the hinge, thereby realizing the opening and closing of the top cover and the skirt structure, thus preventing the odor of garbage inside the trash can from escaping when the trash can is not in use, and making it easy to open the top cover when it is closed.
[0015] Preferably, the lower end face of the top cover is provided with two support arms symmetrically near the hinge point with the skirt structure. The support arms are U-shaped structures. One end of the support arm is fixedly connected to the top cover, and the other end of the support arm is hinged to the lower end face of the skirt structure and a torsion spring is wound between the support arm and the skirt structure.
[0016] When the top cover is fastened within the skirt structure, the torsion spring is compressed and deformed; when the top cover is unlocked by the fastener, the torsion spring automatically opens the top cover through its own elasticity, thus making it easy for the user to open the top cover without direct contact.
[0017] Preferably, the upper opening of the outer shell has a notch, and the fastener is hinged between the two side walls of the notch. The fastener includes a protrusion located near one end of the upper cover, and the upper cover has a barb at the position corresponding to the protrusion, thereby realizing the fastener locking the upper cover.
[0018] Preferably, the fastening member includes a protrusion, a hinge, and a trigger, arranged sequentially from the side near the top cover to the side away from the top cover. The notch includes a swing groove located on the inner side and corresponding to the hinge and a support groove located on the outer side and corresponding to the trigger. The cross-section of the swing groove is an inverted trapezoid that is wider at the top and narrower at the bottom. The hinge point of the hinge extends downward to the lower end of the swing groove, and the hinge point of the hinge is located directly below the protrusion.
[0019] Under the action of the hinge, when the trigger part of the fastener is subjected to force, the protrusion of the fastener can swing away from the top cover, thereby unlocking the fastener from the top cover.
[0020] Preferably, a movable space for the fastener to swing is formed between the trigger part and the bottom of the support groove, and an elastic element is provided between the trigger part and the bottom of the support groove to allow the fastener to return to its initial position.
[0021] The elastic element can be a spring connected between the trigger part and the bottom of the support groove, or an elastic filler filling the space between the trigger part and the bottom of the support groove.
[0022] The support groove limits the swinging motion of the fastener to prevent the user from breaking the hinge of the fastener, and the elastic element supports the fastener so that the fastener can always lock the cover in the normal state.
[0023] Compared with the prior art, the beneficial effects of this utility model are:
[0024] This invention utilizes a top-to-bottom arrangement of through holes in the enclosure structure to create physical ventilation channels. Combined with the constricted shape of the enclosure structure, this forms a gas expulsion path during the user's action of smoothing the garbage bag, forcing the gas inside the bin to be expelled through the through holes. This solves the air resistance problem between the outer surface of the garbage bag and the inner surface of the enclosure structure. Furthermore, the use of a ring-shaped fastener to press down the excess portion of the garbage bag and fold it outwards prevents the garbage bag from slipping and facilitates the full expansion of the garbage bag's internal space for garbage collection.
[0025] This invention features a self-flipping lid on the bin body, allowing users to easily close the bin when not in use and open it without direct contact when needed, thus facilitating user operation. Attached Figure Description

[0034] The present invention will now be further described with reference to the accompanying drawings and specific embodiments.
[0035] like Figure 1 As shown, this embodiment discloses a trash can, including a base 11 for holding trash bags and an outer shell 12 fitted over the base 11. Both the base 11 and the outer shell 12 are made of an elastic, variable material, such as plastic. Figure 2 As shown, the base 11 includes a chassis 13 detachably connected to the chassis 13 and an inner liner 14 disposed on the chassis 13. The inner liner 14 has a square enclosure structure, and a slot 18 is provided at the lower end of the inner liner 14. The chassis 13 is provided with a buckle 19 that cooperates with the slot 18. The inner liner 14 is engaged with the buckle 19 on the chassis 13 through the slot 18, thereby realizing the detachable connection between the inner liner 14 and the chassis 13. Figure 3 , Figure 4As shown, slots 16 are provided on both sides of the inner liner 14 in the width direction. An annular fastener 17 is provided in the slot 16. The annular fastener 17 can be embedded in the slot 16. A plum blossom through hole 171 is provided at the axial position of the annular fastener 17. Through holes 15 are arranged in an array on the circumferential side wall of the inner liner 14. The through holes 15 are arranged sequentially from top to bottom along the height direction of the inner liner 14. The inner liner 14 has a constricted shape that is wider at the bottom and narrower at the top.
[0036] The upper end of the outer shell 12 is also provided with a skirt structure 121 extending towards the center line. The skirt structure 121 is used to fit against the upper end surface of the inner liner 14. A top cover 20 is also provided inside the skirt structure 121. One edge of the top cover 20 is hinged to the skirt structure 121. Figure 7 As shown, two U-shaped arms 21 are symmetrically provided on the lower end face of the upper cover 20 near the hinge point with the skirt structure 121. One end of the U-shaped arm 21 is fixedly connected to the upper cover 20, and the other end of the two U-shaped arms 21 is hinged to the lower end face of the skirt structure 121. A torsion spring 22 is wound around the hinge position of the U-shaped arm 21 and the skirt structure 121.
[0037] like Figure 5 As shown, a fastening member 24 is provided between the other end of the upper cover 20 relative to the U-shaped arm 21 and the skirt structure 121. A notch 23 is provided at the upper opening of the outer shell 12 corresponding to the position of the fastening member 24. The fastening member 24 is hinged between the two side walls of the notch 23. When the user presses the fastening member 24, the fastening member 24 is unlocked from the upper cover 20, and the torsion spring 22 causes the upper cover 20 to open by means of elasticity.
[0038] like Figure 6 As shown, the fastener 24 includes a protrusion 241, a hinge 242, and a trigger 243 arranged sequentially from the side near the top cover 20 to the side away from the top cover 20. The top cover 20 is provided with a barb 201 corresponding to the position of the protrusion 241. The notch 23 includes a swing groove 231 located on the inner side and corresponding to the hinge 242 and a support groove 232 located on the outer side and corresponding to the trigger 243. The cross-section of the swing groove 231 is an inverted trapezoid that is wider at the top and narrower at the bottom. The hinge point of the hinge 242 extends downward to the lower end of the swing groove 231. The hinge point of the hinge 242 is located directly below the protrusion 241.
[0039] An active space 25 for the fastener 24 to swing is formed between the trigger part 243 and the bottom of the support groove 232. An elastic element for the fastener 24 to return to its initial position is provided between the trigger part 243 and the bottom of the support groove 232. The elastic element is a thrust spring 26.
[0040] When a garbage bag needs to be placed inside, the user opens the garbage bag and places it into the inner liner 14. The user then smooths the inner surface of the garbage bag from top to bottom, so that the outer surface of the garbage bag fits against the inner surface of the inner liner 14. During this process, the smoothing action can expel the air between the outer surface of the garbage bag and the inner surface of the inner liner 14 through the through hole 15, and fold the excess part of the garbage bag outward so that it fits over the outer surface of the inner liner 14, thus making the garbage bag fit completely inside the garbage can. Then, the outer shell 12 is fastened onto the inner liner with the garbage bag, and the skirt structure 121 is attached to the upper end of the inner liner 14, thereby pressing the garbage bag tightly.
[0041] When the top cover 20 needs to be opened, the user can press the trigger part 243. The trigger part 243 drives the hinge part 242 to swing away from the top cover 20 in the swing groove 231, thereby causing the protrusion 241 to disengage from the barb part 201 of the top cover 20. At this time, the top cover 20 is unlocked, and the elastic force of the torsion spring 22 causes the top cover 20 to open through the U-shaped arm 21. When the top cover 20 needs to be fastened, the top cover 20 is pressed down, and the lower end face of the barb part 201 abuts against the protrusion 241, causing the protrusion 241 to swing away from the top cover 20 again, so that the barb part 201 moves back to the lower end of the protrusion 241, and the protrusion 241 locks the top cover 20 again through the barb part 201.
